Description
Technical field：
The utility model belongs to stamping Die Design technical field, is related to the processes such as a kind of blanking, trimming, punching, bending
Progressive die, more particularly to a kind of fastener member punching progressive die.
Background technology：
Stamping die is also referred to as cold-punching mold, is commonly called as cold-punching mould.Stamping die is in Cold Press Working, by material（Metal
It is or nonmetallic）It is processed into part（Or semi-finished product）A kind of special process equipment.Punching press is at room temperature, using installed in pressure
Mould on machine applies pressure to material, it is produced separation or plastic deformation, so that a kind of pressure of part adds needed for obtaining
Work method.Stamping die is the essential technological equipment of punching production, is technology-intensive product.The quality of stamping parts, life
Efficiency and production cost etc. are produced, has direct relation with mold design and manufacture.The height of Mould design and manufacturing technical merit,
It is the one of the important signs that for weighing a national product manufacture level height, largely decides quality, the effect of product
The development ability of benefit and new product.
The content of the invention：
The utility model aim is to design a kind of fastener member punching progressive die, and a kind of warp is provided for fastener member manufacturing industry
The multi-station progressive die that Ji property is good, efficient, punching precision is high, takes so that the production cost of fastener member is reduced and improved
The precision of fastener.
To achieve these goals, the utility model provides following technical scheme：A kind of fastener member punching progressive die, the mould
Tool includes：Guide sleeve, hexagon socket cap head screw, straight pin, blanking punch, bending punch-pin, die shank, trimming punch, convex mould pad,
Side edge, punch retainer, unloading bolt, upper mold seat, piercing punch, stripper, interior stock guide, guide post, cavity plate backing plate, discharging
The part groups such as spring, slotted cheese head screw, pilot pin, fluting headless screw, die block, cavity plate, straight pin, die holder
Dress forms.Reciprocating part of the upper die and fixed part of the lower die can be divided into by entirely assembling complete mould.
The reciprocating part of the upper die is by upper mold seat, convex mould pad, punch retainer, punch-pin and stripper
This five big component composition.Realized wherein between upper mold seat, convex mould pad, punch retainer using six hexagon socket cap head screws
Fastening and four straight pins are realized precisely installation and are coordinated.
Forced die shank is housed in the upper mold seat of the reciprocating part of the upper die, fixed form by die shank convex shoulder
With the fit depressions of upper mold seat.The effect of die shank is that the power of mold exterior forcing press is delivered in mould, is mould
Punching press provides power, and the center line of die shank and the Center of Pressure of mould coincide.It is accurate when Center of Pressure is calculated
Calculate, find accurate Center of Pressure, otherwise in punching serious unbalance loading can occur in a flash for part of the upper die, so both influence
The service life of mould, while also so that the quality of the blanking part of punching declines.
The effect of the convex mould pad of the reciprocating part of the upper die is enhancing punch-pin during plate is cut
Rigidity between upper mold seat, is buffered in the moment for cutting plate to the suddenly change of upper mold seat pressure, reduces upper mold
The deformation extent of seat.Therefore convex mould pad not only plays the role of improving die life, but also plays the work for improving part accuracy
With.
The punch-pin is divided into piercing punch, side edge, trimming punch and bending punch-pin, blanking punch.This five classes punch-pin
Type is salient shoulder type punch-pin, and fixation is realized using the groove of its convex shoulder and punch retainer.The function of piercing punch is punching
One of fastener member10 and four3.2 hole.Side edge not only plays the role of trimming, but also plays billot and be sent into just positioning
Effect.The function of trimming punch is the semi arch that punching goes out R10.The function of bending punch-pin is so that template blank bends to 90 degree
It is pressed into the shape of blanking part.Blanking punch is last procedure of mould, its function makes product that bending gets well from billot
Face is shear off, and becomes independent part.
The discharging of the reciprocating part of the upper die is attached by unloading bolt and part of the upper die.In discharging
Played a supportive role between plate and punch retainer by discharging spring, it is with the motion state of the movement of upper mold seat --- when upper
When die holder is in upper extreme position, the lower plane of stripper is equal with the lower face of punch-pin.As upper mold seat moves downward, until
When punch-pin arrives at plate upper surface, discharging spring starts to compress so that stripper is pressed on the upper surface of plate.When punching is completed
When, upper mold seat moves upwards, and stripper stops that waste material continues to move up while punch-pin departs from cavity plate so that waste material smoothly departs from
Punch-pin.Therefore, elastic discharging flitch serves a dual purpose --- the effect of binder and discharging.
The fixed part of the lower die is by die holder, cavity plate backing plate, die block and cavity plate four main zero
Part part forms.Wherein between die holder, cavity plate backing plate, die block three fastening is realized with four hexagon socket cap head screws
Precisely installation is realized with four straight pins and is coordinated.Realized between die block and cavity plate with six hexagon socket cap head screws
Fastening and four straight pins are realized precisely installation and are coordinated.Four major parts are so made to be assembled into the lower mold portion of an entirety
Point.
The effect of the die holder of the fixed part of the lower die is carrying fastener punching progressive die part.Its lower surface
Contact, be placed on forcing press with the forcing press of mold exterior；Surface support cavity plate backing plate thereon.
The cavity plate backing plate effect of the fixed part of the lower die is similar to the effect of convex mould pad, rises and is buffered in cutting
The suddenly change of the moment die holder pressure of plate, reduces the deformation extent of die holder.Therefore cavity plate backing plate both played
The effect of protection die life, and play the role of improving part accuracy.
The die block of the fixed part of the lower die is to make cavity plate is safe and reliable to consolidate with cavity plate phase separation
It is fixed motionless, and then ensure to cause precise match between cavity plate and punch-pin, so as to ensure that the accuracy class of blanking part.
The interior stock guide is fixed on cavity plate top, and fastening is realized with four slotted cheese head screws.Interior guide
Board-like effect is the punching position for guiding billot smoothly to enter mould.
The structure of the pilot pin is salient shoulder type, essentially the same with piercing punch.Its convex shoulder part is placed on the heavy of stripper
In head bore, the top of counter sink, which is arranged with, is threaded into fluting headless screw, prevents pilot pin from coming off.
The guide post is for supporting part of the upper die, and is play the guiding role in the motion process of upper mold.Guide post lower end is straight
Connect tight fit and die holder, upper end loose fit and guide sleeve, guide sleeve and upper mold seat tight fit.So so that part of the upper die and lower mold portion
Divide and form an entirety, form fastener punching progressive die.
